Need backpack for tall person

[stitch58]

I was wondering if anyone could recommend a backpack style camera bag made to fit tall people? I'm 6'4" & can't seem to find a bag that fits. If possible I prefer a pack that is divided, one compartment for camera gear & one for rain gear, snacks ,etc. . It should also be capable of carrying a tripod & adjustable harness that includes a padded waist belt & sternum strap. Thanks !!
